The native of Fort Erie, Ontario spent four years with the OHA's St. Catharines Teepees and helped the club win the Memorial Cup in 1960. The parent Chicago Black Hawks sent him to the minors to develop. After scoring 75 points in 70 games for the St. Louis Braves in 1963-64, he was named to the Central League first all-star team. Chicago used Brenneman for 17 games in 1964-65 but they had Doug Mohns, Camille Henry, and youngster Dennis Hull at left wing. Before the end of the season he was traded to the New York Rangers where he played the last 22 games of the schedule.

In June 1966, Brenneman was claimed by the Toronto Maple Leafs in the intra-league draft. He played 41 games in 1966-67 when the club experienced injuries and the doldrums but he was not around for the Stanley Cup win. He later toiled with the Detroit Red Wings and Oakland Seals before retiring in 1969. He came out of retirement to play for the IHL's Dayton Gems in 1970-71 and the senior Cambridge Hornets three years later before calling it quits for good.
